Abstract

A composition comprising iodotrimethylsilane in admixture with a polysiloxane is shelf stable for a long time and effective in various organic synthetic reactions.

Claims

exact text as granted — not AI-modified

We claim: 
     
       1. An iodotrimethylsilane composition comprising iodotrimethylsilane in admixture with at least one member selected from polysiloxanes of the general formulae: ##STR5## wherein R 1 , R 2 , R 3 , R 4 , R 5 , R 6 , R 7 , and R 8  are independently selected from monovalent hydrocarbon groups having 1 to 6 carbon atoms, letter m is an integer of from 1 to 100, and n is an integer of from 3 to 100. 
     
     
       2. The composition of claim 1 wherein the polysiloxane is hexamethyldisiloxane. 
     
     
       3. The composition of claim 1 wherein the polysiloxane is octamethylcyclotetrasiloxane. 
     
     
       4. The composition of claim 1 which contains 70 to 30 mol % of the iodotrimethylsilane and 30 to 70 mol % of the polysiloxane.
